some from wood, or a bottle, with a metalic mesh net over other so they cant get stuck, you can let them roll around and when picked on treats or Food falls out, or hang it up even different ones (like on a branch you did hang low with an other a bit higher up and at those you hang the feeder and toys^^)so they have to work more hard or easy for there food...but still watch if they get enough maybe put part in the bowl and part in the toys and foraging feeder.
i once did see some interesting Thing with an small strwa bale and bark and some branches, with some with leaves for the chicken to eat...or food in ood (like a apple willed with reisin or insects the birds like, with small holes to pick them out and such things^^)
some birds learn fast other slow, some work bether with one Thing other with an other, so try out what works for all or use two three feeder or toys^^
but always watch that they all still get enough, that they cant get stuck or hurt, no sharp places or such, and bird helthy wood^^
hope you tell when you try something or even show pic when something really works well
